This invention discloses a method for interpreting non-uniform fracture parameters based on fracture propagation simulation forward modeling and pump shutdown pressure drop analysis inversion. The method includes: (1) obtaining geological parameters and construction parameters of the target well, and obtaining pressure data based on the fracturing construction process; (2) using cepstral analysis to identify the opening status of multiple perforation clusters in a single fracturing section based on high-frequency pressure data, and determining the location of the effectively opened perforation clusters among all perforation clusters; (3) using low-frequency pressure data to obtain the total area of ​​the first fracture in a single fracturing section based on the inversion theoretical model; (4) establishing a fracture propagation simulation model, using the location of the effectively opened perforation clusters and the total area of ​​the first fracture as physical constraints, and simulating the total area of ​​the second fracture. When the difference between the total area of ​​the second fracture and the total area of ​​the first fracture is less than a set threshold, the interpretation of non-uniform fracture parameters in a single fracturing section is achieved. This invention can achieve rapid and accurate interpretation of non-uniform fracture parameters.

This application provides a method and system for bandgap prediction and interpretation based on a multi-head self-attention mechanism. The method includes: using a Transformer-based encoder to model the global dependencies of a CSV file containing the physicochemical characteristics of lithium-ion battery materials through a multi-head self-attention mechanism, determining the context embedding, and concatenating it with the physicochemical characteristics of the lithium-ion battery materials to determine training features; then using a pre-set CatBoost regressor to perform regression training on the training features to determine the Catformer model; using the Catformer model to predict the bandgap of the lithium-ion battery material to be tested, and using the SHAP analysis method to perform interpretability analysis on the bandgap prediction. This application enhances the global dependency characteristics of the material, achieves accurate bandgap prediction, and reveals the physicochemical significance of the prediction results, providing a general tool for the rapid design of lithium battery electrode materials.
